Gmail : Add location to your signature

Gmail labs today added a feature which allows user to add a location to the signature of the email. This feature can be enabled from Gmail settings.

Gmail identifies location in 2 ways with different degree of accuracy.

1) By finding location depneding upon IP address of the email sender.
2) By Google Gears location module. (More accurate)

This feature comes from Gmail labs which has been adding features developed by Gmail developers in their 20% time working on the project of their interest. Gmail itself was started as someone's 20% project.

Gmail has been adding feaures to labs quite frequenly over last few weeks. Not all of these features are guranteed to be available. Google has been following model of leaving test new features for its products before adding it for all the users.
